The largest rescue operation of German concentration camp prisoners in World War II was conducted by the Swedish Red Cross, who used distinctive white buses to transport 17,000 refugees from Ravensbruck in a harrowing expedition through the war-torn countryside during March and April of 1945. Led by Count Bernadotte of Wisborg, the mission was arranged through secret negotiations with SS chief Heinrich Himmler, who hoped to negotiate his own surrender of Germany. This is the first book in English to detail this remarkable and hazardous operation, and with previously unpublished photographs.
